Abstract: Wind turbine cable connector monitoring method and device for monitoring a connector (1) attached to cable (4). A temperature sensor (6) is provided for sensing a measured temperature at a position a known distance along the cable (4) from the connector (1). A controller (8,19) records the measured temperature from the temperature sensor (6) while the connector (4) is in use, and identifies a potential fault condition in the connector (4) based on the measured temperature and the position the known distance along the cable (4) from the connector (1).
